Meiosis stages diagram. The process of meiosis involves two steps. Meiosis i and meiosis ii. The stages of meiosis can be studied through the diagrams above.

The two stages of meiosis are meiosis i and meiosis ii. This is the currently selected item. Each of these two steps of meiosis has stages just as in mitosis.

Phases of meiosis i. Explanation of each step with the stages will be described below with diagrams to help in understanding. Phases of meiosis ii.

Draw and describe the stages while you are also revisiting the concept of meiosis. Prophase metaphase anaphase and telophase. At the end of the meiotic process four daughter cells are produced.

Mitosis is the simplest of the two ways mitosis and meiosis in which the nucleus of a cell can divide as part of a process of whole cell division. The four stages of mitosis prophase metaphase anaphase and telophase are shown and described below. The nuclear envelope degrades which allows the microtubules originating from the centrioles on either side of the cell to attach to the kinetochores in the centromeres of each chromosome.

Meiosis is a cell division process that occurs in two stages resulting in the formation of four haploid gametes. Meiosis i and meiosis ii. Biology is brought to you with support from the.

Each stage is further divided into another four phases details of which we will discuss in this article. Meiosis consists of two divisions both of which follow the same stages as mitosis prophase metaphase anaphase telophase meiosis is preceded by interphase in which dna is replicated to produce chromosomes consisting of two sister chromatids. Differing from the metaphase stage of mitosis the centromeres of chromosome pairs in metaphase stage of meiosis i become attached with the spindle fibres near the equatorial region.

From greek μείωσις meiosis which means lessening is a special type of cell division that reduces the chromosome number by half creating four haploid cells each genetically distinct from the parent cell that gave rise to them. The centromeres remain clearly apart from each other and face the opposite poles while the arms of the chromosome pairs lie towards the equator. Prophase i the first step in meiosis i is similar to prophase in mitosis in that the chromosomes condense and move towards the middle of the cell.

A second growth phase called interkinesis may occur between meiosis i and ii however no dna replication occurs in this stage. Meiosis stages prophase i. Meiosis m aɪ ˈ oʊ s ɪ s.

There are two stages or phases of meiosis. Try to identify the stages of meiosis using the unlabeled diagrams.
